Fully Qualified Domain Name (FQDN)

Fully Qualified Domain Name (FQDN) is a domain name that specifies its exact location in the tree hierarchy of the Domain Name System (DNS). It specifies all domain levels, including the top-level domain and the root zone. A fully qualified domain name is distinguished by its unambiguity; it can only be interpreted one way.

Solaris equivalent of hostname -f?

What is the Solaris equivalent of the Linux hostname -f command? On Solaris, when I type hostname, I receive the short name but I need to get the FQDN. Typing hostname -f sets the short name to be "-f", and the manpage for hostname is pitiful.
